ICE-CREAM FR'EEZER.

SPECIFICATION forming partrof Letters Patent No. 252,254, dated January 10, 1882. Application led J' une 16, 1881. (No mode-l.)

To alt whom it may concern:

Be 1t known that I, MICHAEL RIOHEIMER., a

`citizen of the United States of America, residing at Massillon, in the county of Stark and 4tion, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, whichl form a part-of this speciication.

This invention relates to improvements in ice-cream freezers of that class in which use is made of a reciprocating dasher or plunger, a rotating cream-vessel, a cogged cover for said vessel, a crank for reciprocating the dasher or plunger, and a gear mechanism for rotatingV the cream-vessel. y

Figure l is a front View of the device. 2 is a vertical section.

In the drawings, Arepresents a bed-frame for holding the stationary parts. To this bedframe'is secured an upright frame for the support ofthe power devices., This latter frame is composed of two uprights, B B, carried by expanded supports b b at the bottom.

C represents a shaft mounted horizontally in theuprights B B. It carries a largel spurwheel, D, between the uprights, a small pinion, E, at the inner end, and a crank, F, at the outer end.

l,Above and parallel to the shaftV C another shaft, G, is mounted. It carries a spur-pinion, H, meshing with Wheel D between the uprights B B, and carries a crank-wheel, I, at its inner end. This upper shaft, G, projectsinward farther than the shaft C, for a. purpose to be set forth hereinafter.

J represents the ice-tnb, withinwhich is placed the cream-vesselK. The tub J is rmly held in place by means of strong uprights LL and a raised portion, a, ot' the bed A. The cover of the cream-vessel is formed with a central tube or hollow boss, k, which provides a support for theupper end of the cream-vessel, and also permits the passage ot' the dasherrod.

Eig.

M is a bar, which can be securely attached tothe top of the uprights L L, and which has a central aperture for the mounting of the tube or boss k.

The cover is provided also with a crown spurgear, l, which, when the parts are in working position, meshes with thepinion E.

m is the dasher, and M the rod attached thereto for reciprocating it. The rod is pivoted to a pitman, N, which is in turn pivoted to the crankwheel I. The shaft G projects inward far enough to bring the pitman directly 1'I1 the Vertical plane of the dasher-rod. By means of a pin or pivot at n the pitman and rod Ml are detachably connected together.

In operation-the tub J, after the cream-vessel and the ice have been introduced,is pushed back until the pinion E is in gear with the crown-Wheel l, the uprights L L serving to guide the tub and to brace it. The har M is then placed in position and fastened by pins o o passing through studs m m', projecting upward from the uprights. The pitman N is then pivoted to the rod M', and the device is ready for working. If the crank F be rotated, the cream-vessel will be revolved by the. pinion E and wheel l and the dasher will be reciprocated by the crank-wheel I and the pitman N.

I am aware thatr heretofore use has been made of gearing and cranks to produce simultaneously a rotation of the cream-vessel and a reciprocation of' the dasher, such devicesbeing shown in the patents to Lipp, No. 62,429, February 26, 1867, and Bote, No. 113,450, April 4, 1871; and I do not claim, broadly, such devices as my invention; but the devices that have been heretofore used for these purposes have not been combined With the icetub andthe cream-vessel in the manner which I employ, nor has the gearing used been of the' nature of mine. I so arrange the ice-,tub relatively to the gearing-trame andcornbine With it uprights ot' such nature that it can be held Iirmly in position both at thevtop and bottomindependentl;T of said gearing-trame, and yet at the same time allow ot' its being independently detached from said gearing-frame Without moving the latter.

What I claim is- Sho IOO
